Sounds good. Definitely let us know if you are able to get a BSOD (instead of a complete shutdown) so we can maybe analyze the Stop Code.
Better yet, I’m hoping the problem resolves itself. Don’t laugh…In the 25 years I’ve been working with PC’s I’ve seen it happen more than once.
Unfortunately there is nothing, it just resets without any error screen or code 
Before it began to crash the only changes made were: nvidia driver updated and the fenix updated, I think I’ll just stick to the 737-800 until the next GPU driver update, fenix update, or maybe even SU15. As for the self repair miracles, I’ve seen many and was hoping for one here, but it reset right before touchdown 
after exact 1h:20 on the elapsed timer that I start right when I begin the takeoff roll (It’s like if there was some internal countdown leading to the restart at this time frame just to troll me). But well, let’s hope something brings the stability back, whatever update it is. 
Forgive the question, but you did turn off automatic restart, right?
I wonder if this Automatic restart means upon system failure the system shuts down and then restart itself when enabled. But when disabled, upon system failure the system just shuts down and that’s it. Not restarting afterwards?
Or does it completely prevent the shuts down process entirely upon system failure?
Nothing can prevent a total shutdown/restart (depending on how the BIOS is configured) from a loss of power, like when a PSU fails, or a motherboard fails, or a CPU overheats.
But I’m pretty sure if something else occurs, like RAM failure, or an OS kernel dump, having automatic restart disabled would result in a BSOD, and not a system reset.
Yep, as I should have according to posts before, but it did nothing, then I decided to try with fenix setting activating alternative render, and in the game’s settings I set it to DX12, it crashed to desktop after 15 minutes instead of a total reset, then I switched off the alt rendering and left just DX12, and somehow and unexpectedly it decided to work for a lot longer than the usual 1:20 without a single issue:
I had a similar issue, but worse, after the last update, I hadn’t play the game for a few months, and now I wanted to go on a flight, but first decided to download and install some free content from the market place, and bam, black screen WHILE the sound still went on for a while, then PC REBOOTED itself. I launched the game again, clicked on the marketplace/store, AGAIN and AT ONCE the black screen appeared, then Windows didn’t want to start, or rather, there was no picture, since I noticed my graphic card had gone dark while the PC was apparently on. I switched the PSU off, then back on, then started the PC, and to my great relief it booted up normally. I almost thought MSFS had killed my GC.
WHAT are you doing out there with this game ? This kind of thing never happened on this game or any other game for that matter before on my PC (Windows 10). Now I am actually afraid of launching the bloody game for fear of hardware or software damage!!!
Forget I said anything, turns out I do have a hardware problem “as of now”… just made a “test” on Cyberpunk 2077 and the same thing happened, I noticed this time that the graphic card had switched itself off mid game… great…
I had a very similar issue. The PC restarted during a flight with the Fenix A320 sporadically and since SU_15 regularly. The difference: I did not have any system log for that, it was like the power has been switched off suddenly during a flight. I did not have this issue with any other airplane or game. And it did not happen after 20 and after 80 minutes like in your case, it was just arbitrary.
Finally after some investigation I disabled XMP memory profile in BIOS (which is a high performance memory profile with quite low timings). I just switched to default timings … and the issue is gone at least after first 8 hours of testing. Previously I got the warm start mostly within 30 minutes.
XMP is the first thing to look at BIOS!
Hi @xDaniel42 did you ever resolve your issue fully? I’m having the exact same problem now where I can complete flights in the FBW A32N but the Fenix seems to consistently cause a reboot at an arbitrary moment during the whole flight process (could be 2 mins, could be whilst taxiing, could be during the descent, but I am yet to complete a full flight in it since this issue began). I’ve had no issues in any other games or applications yet either, it seems to be exclusive to MSFS and the Fenix in particular.
I’ve tried pretty much every solution posted online and ended up taking the expensive way out of ordering a new MOBO, CPU, and RAM to see if that will fix it - but if there was a fix that worked for you I’d be keen to try it! 
I had this happen recently in SU1, thought it was my 1000w PSU, was flying the FBW A320 i think.
Complete shutdown of my pc after 30 minutes like a power cut, no BSOD , but there was a log in event viewer that i had not heard of before.
Cannot remeber what it was though the pc
Rebooted straight after
Temperatures on cpu and graphics card were in the late 50’s early 60,s celsius throughout gaming.
Ran unigine that was fine, ran cpu stress tests , no problem and then ran memtest with xmp still enabled on 3600mhz 64gb ram, which took over 5 hours and it passed.
Never had this in msfs2020 ( Ihave and fly the Fenix) never had this issue in any other game before, havent had it since although i dont fly 2024 that often but have done a couple of 2 hour flights.
Msfs2020 i do long flights and its always been fine so there must be something on 2024 that is causing this.
In your case I would try memtest86 and see if that throws any errors, technically you should disable xmp ( i didn’t) and you can try single sticks of ram although if you have two or more and it does throw an error you should replace all from the same vendor , dont mix ram even if its the same mhz.
What CPU do you have , have you overclocked or undervolted it ? You can try a few 30 minute cinebench tests to see if its stable and temps are fine,
Plus have you overclocked your graphics card?
Hope you get it sorted
Have you tried rolling back your nvidia driver to the december release? The 572 drivers are terrible try the 566 ones.
Why terrible? I’ve been using this with no issues…
For me the issue stopped happening after switching to balanced power mode, maybe something was wrong with the performance plan and usage spikes of the fenix (happen less now I think)
Same here. I clung to 566.36 for a long time (it was a great driver…)
I’ve been on 572.83 for several months and it’s working great. I don’t use the nVidia App or GeForce Experience.
To be fair it tends to be on multiple monitor setups. of you are using a single monitor setup it tends to be ok, but not guaranteed. And I have a multi monitor setup.
I have a 32" 4K monitor that the sim runs on, and a 24" 2K monitor for other apps. I know that configuration is different from those running the sim interface across multiple monitors. Maybe that’s why I’m not having a problem? Seems odd, though.
